Abstract
A hoister head sheave rotation angle detection device comprises a head sheave platform for erecting a head sheave, a coupler, an encoder, a single chip microcomputer and an industrial personal computer, and a guiding device is mounted on the head sheave platform. When the head sheave runs, a guide spindle and an auxiliary guide shaft which are symmetrically clamped on two sides of a head sheave spoke rotate under the action of friction force, received rotation angle signals of the guide spindle are transmitted to the single chip microcomputer by the encoder connected to the tail of the guide spindle, the single chip microcomputer is connected with the encoder, the acquired rotation angle signals sequentially pass through an RS232-to-RS485 converter, an RS485 cable and an RS485-to-USB converter and are finally transmitted to the industrial personal computer for processing, and thereby rotation angles of the hoister head sheave are monitored in real time. The hoister head sheave rotation angle detection device adopting the method avoids modification and processing of a head sheave end cover, reduces impacts of radial and axial vibration of the head sheave to the encoder, is simple in structure, and is applicable to angle detection of a head sheave with higher parallelism on two lateral surfaces of a spoke.
